Like many vernacular regions, Central Florida's boundaries are not official or consistent, and are defined differently by different sources. A 2007 study of Florida's regions by geographers Ary Lamme and Raymond K. Oldakowski found that Floridians surveyed identified Central Florida as comprising a large swath of peninsular Florida.[1] This area encompassed the interior, including the Orlando metropolitan area, and coastal stretches from the Big Bend south to the Tampa Bay Area in the west and from Daytona Beach south to Martin County in the east. In addition, North Central Florida has emerged as a vernacular region representing the interior area in the northern part of the state.[1]

Central Florida is one of Florida's three most common directional regions, the others being North Florida and South Florida. Lamme and Oldakowski note that the directional region is more commonly used in the interior areas rather than on the coast.[2] In fact, while coastal areas often have their own regional vernacular identities such as the Space Coast and the Nature Coast, no vernacular regions were reported on the interior of the state other than Central Florida.[1]

The central cities of both metropolitan areas (Orlando and Tampa) are in close proximity (85 miles (137 km)), and as a result, their two metropolitan areas blend together in the area of Lakeland to make up a larger contiguous population center often referred to as the I-4 corridor.[4][5] This is a population concentration that stretches from Tampa Bay on the west coast to Daytona Beach and Cape Canaveral on the east coast of the state.

With the exception of hill terrain in southern Lake County, Hernando County, Pasco County and Polk County, Central Florida is mostly flatland with significant amounts of open space and over 1,500 lakes and ponds. There is a mixture of wetlands, Cypress, Oak, Maple and Pine forests, pastures, prairies and coastline.[6]

Winters are dry and temperate with the average winter high temperature in Orlando being 72 °F (22 °C).[8][9] Summers are hot and humid with high temperatures averaging 92 °F (33 °C). Peak summer heat generally arrives in early June and continues to early October.[10][11]

The combination of high temperatures, high humidity, and opposing sea breezes from both the Gulf and Atlantic coasts, results in significant thunderstorm activity from June to September for the interior counties. Central Florida records more lightning strikes per area than any other region in Florida, and Florida records more lightning strikes than any other state in the USA. As a result, Florida, and more specifically, Central Florida, is often referred to as the "Thunderstorm capital of the USA",[12][13] or "Lightning Alley".

These severe thunderstorms often make Central Florida prone to many tornadoes. However, they are usually small, short lived, and almost always rated as EF0 or EF1 size storms.

At the end of the Civil War most of Central Florida was barely-inhabitable wetlands. It took a major drainage project financed by Philadelphia businessman Hamilton Disston in the 1880s to make the land available for settlement.

Sanford was incorporated in 1877 as port city at the intersection of Lake Monroe and the St. Johns River. It was envisioned as a transportation center, the city's founder, Henry S. Sanford, nicknamed it "the Gate City of South Florida". It became a hub for shipping agricultural products, which earned the city another nickname, "Celery City".

Kissimmee boomed in the 1880s. It was the headquarters of Hamilton Disston's drainage company, The city was an important regional steamship port, owing that status to its location on Lake Tohopekaliga. The expansion of the railroads into Central Florida eliminated the need for Kissimmee's steamship industry.[14]

The Great Freeze of 1894-95 ruined citrus crops which had a detrimental ripple effect on the economy.[15]

The hard-packed sand of Volusia County's beaches lent itself to auto races beginning in 1903, before paved roads were common, leading to the area's reputation for cars and racing. Ormond Beach was a popular spot for those who liked fast cars after the turn of the 20th century because the hard-packed beach was ideal for going fast. That same beach had led to the development of a tourist resort by Henry Flagler. It later attracted Flagler's former business partner John D. Rockefeller, who had a winter home in Ormond.

During and after World War II, the U.S. Army Air Forces (U.S. Air Force after 1947) and the U.S. Navy established several training facilities and operational bases in the region, mainly aviation activities, later followed by space exploration sites. In the late 1940s, the US military established a missile testing facility on Merritt Island near Cape Canaveral because the land was largely undeveloped and the agreeable climate allowed for year-round operations. When NASA later searched for a long-term base in the 1960s from which to launch spacecraft, they chose the adjacent Merritt Island site next to Cape Canaveral for its access to the testing facility and to nearby communities. NASA purchased over 100,000 acres (400 km2) of land for the Kennedy Space Center.

Deltona was developed in 1962 as a planned retirement community. It is now the largest city in Volusia County.

The construction of the Walt Disney World Resort was a transforming event for greater Orlando. Walt Disney wanted a location with abundant available land that was more accessible for the residents of the eastern United States to visit. Not only was there ample land in Central Florida, but it was inexpensive and the inland location offered some protection from hurricanes. Plans were announced in 1965, and the theme park opened to the public in 1971.[14]

Lamme and Oldakowski's survey identifies several demographic, political, and cultural elements that characterize Central Florida and distinguish it from other areas of the state. While people from all parts of the state associated their area as part of the South, people in the southern part of Central Florida did not typically identify their area as part of "Dixie", while people in northern Central Florida did. People from Central Florida usually did not consider their region part of the Bible Belt.[1]

Politically, while North Florida overwhelmingly was considered conservative and South Florida was considered more liberal, the majority of Central Florida residents (52%) considered their area moderate; 41% considered it conservative, and 7% liberal.[16] Lamme and Oldakowski's survey tracks with Barney Warf and Cynthia Waddell's studies of Florida's political geography during the 2000 Presidential election.[16][17] Central Florida's economy is very similar to that in South Florida. Compared to the more diversified North Florida economy, tourism is by far the most significant industry in Central and South Florida, along with a much smaller but significant agricultural industry.[18]

Lamme and Oldakowski's survey also found some cultural indicators that characterize Central Florida. In general, Central Florida was similar to North Florida and differed from South Florida in these measures. In Central and North Florida, American cuisine was the most popular food, in contrast to South Florida where ethnic foods were equally popular.[19] Additionally, while there was little geographical variation for most styles of music, there was regional variation for both country and Latin music. Country was popular in Central and North Florida, and less so in South Florida, while Latin was less popular in Central and North Florida, and more so in South Florida.[19]

In 2009, the estimated total population of the Central Florida, including the populations of Orange, Seminole, Osceola, Brevard, Volusia, and Lake Counties region was 3.3 million people.[20] If the populations of Polk, Flagler, and Sumter counties were included, the estimated population would be 3.969 million people.[citation needed] Explosive growth has fueled Central Florida for the past thirty years.

As of 2007 there were 70,000 Asians in Central Florida according to the U.S. Census. There were almost 1,900 Japanese persons, making up 3% of the Asians.[21]

The Tampa Bay area has become a center of high-tech manufacturing and research,[29][30] while both Orlando and the Tampa Bay area are centers for the financial industry, especially insurers and back-end operations for large banking companies.

Port Canaveral, located in Cape Canaveral 45 minutes east of Orlando, is a cruise, cargo, and naval port. It is one of the busiest ports in Florida and is economically tied to Orlando. Locally perceived to be Orlando's seaport, Port Canaveral is the closest port for tourists and Orlando residents alike to cruise on Disney Cruise Lines and Carnival Cruises. Future plans for the port include a rail and natural gas line running directly to Orlando International Airport.

A High Speed Rail line was in the planning stages at one point during the years of 2009-2011, however, that plan was eventually canceled by the Governor of Florida, Rick Scott, after a cost analysis of the project. The train line had been planned to run from the Orlando International Airport to downtown Tampa; with future lines eventually connecting to downtown Orlando, Jacksonville, and Miami.[32]
